Aer Lingus and American Airlines have expanded their codeshare agreement to include transatlantic routes from Dublin to Chicago and Philadelphia.
The deal means customer can now book flights between the destinations on either of the carriers’ websites, allowing for increased connection options.
The move follows the launch of a codeshare agreement between the two airlines last year, initially covering American Airlines domestic routes from Chicago, and Aer Lingus services from Dublin to selected UK and Irish destinations.
It also follows the recent ending of Aer Lingus’s codeshare deal with AA’s rival US carrier United.
Aer Lingus said that the expansion “marks a crucial step forward in Aer Lingus’ arrangement with American Airlines as well as the existing wider Atlantic Joint Business (AJB) partnership, which includes American Airlines, British Airways, Iberia and Finnair”.
The US Department of Transportation (DOT) granted final approval for Aer Lingus to join the existing transatlantic joint venture in December 2020.
